Advanced Data Recovery on Linux

It’s the perfect nightmare and everyone do all his best to avoid it but sooner or later it happens.

Loosing data from a hard disk or a USB device is more common than you can image and everyone has experienced it!

Windows has different commercial solutions available to recover data and partitions but, if you use Linux, you need something different.

The best solution I found for Linux is an old but current article by Lifehacker.au that I strongly recommend if you are experiencing this kind of problems and want to solve them.

“Username is not in the sudoers file. This incident will be reported…” How to add a specific user to sudoers on Linux

Sooner or later, if you use Linux and you prefer Terminal to GUI you will stumble on this message:

Username is not in the sudoers file. This incident will be reported

The first thing to clarify is that the “incident” will never be reported outside your computer but in the auth.log file. But if you have previously configured your Linux OS to send these kind of logs to you by email, you receive an alert about.. your own activity with sudo…

In any case, to solve the above mentioned specific sudo matter, use Terminal and type:

sudo gedit /etc/sudoers

At this point the text file “sudoers” will be opened and you will be able to modify it using e.g. gedit.

Obviously you can use another text editor you prefer as, for example, nano. In this case the command will be:

sudo nano /etc/sudoers

Now you have to peer into the text and find the “#User privilege Specification” section and add the command:

your-username ALL=(ALL:ALL) ALL

where ALL=(ALL:ALL) ALL stands for: allow the specific user (your-username) to access all the terminals, as if he/she were any other user, and allow him/her to execute the full range of commands.

And you will obtain something similar to this:

# User privilege specification
root ALL=(ALL:ALL) ALL
your-username ALL=(ALL:ALL) ALL

Try it! (..if you need…)

If you liked YUMEX, don’t miss YUM EXTENDER (DNF) for Fedora 22

If you are one of them (like me) that prefer to manage and/or install software through an easy to use GUI, don’t forget to migrate to the new version of the “old” YUMEX.
Open your favourite Terminal and type:
su
dnf install yumex-dnf

Follow the instructions that appear on the screen and enjoy the new DNF GUI manager for Fedora 22.

Blogilo: the Linux blog client to create new posts on your local computer

Yes, I know! Talking about Blogilo is not an hot news but the “recent” version 1.1 (according to the Help Menu in Blogilo software) has added some new features and something has changed. Some years ago, when I tested Blogilo, I thought that this software was a good “concept” but it lacked of too many features as compared with e.g. online WordPress.com platform. With version 1.1 these lacks have been reduced and now Blogilo becomes interesting if you are looking for a software that could be used daily for offline posting.
Blogilo now has less bugs than in the past and it is possible to write posts with just few seldom crashes. The user interface is intuitive and after the installation you spend just few minutes for adding and setting your blog. The positive thing is that Blogilo works with all the main blog platforms and it could be considered as one of the most complete blog client for Linux.
The matter is that blog platforms evolve quickly and Blogilo, as all its competitors, seems to be slower than many of them. In fact, it could happen that some up-to-date features are immediately not supported and you have to manually modify your post and adding them directly through the host website (e.g. WordPress). 
One of the most annoying problems I continue to have with Blogilo is about wrapping text around the image/picture I am used to put at the beginning of every post I write. It is a simple matter to solve but at every post I have to manually change the html code. 
As for my experience you have two different ways to solve this isssue.
The first is to edit the image/picture after you inserted it into the post and add the value “allign” selecting the right options in the Advanced Menu (why the Advanced Menu is not available when you insert a new image/picture?).
The second (faster) is to go to the Html Editor tag into Blogilo and add this code at the end of the image <img> tag:
align="left"
For example writing this post I added:
<img src="http://i119.photobucket.com/albums/o158/galigio/blogilo_logo_zps3pmqrnq1.png" align="left" width="160" height="105">
Simple to solve but really annoying when you have so little time to dedicate to your blog….
To sum up it is possible to affirm that Blogilo really contains all the features to write a blog but if you need something more professional you have to spend some hours, after the installation, to learn how to find the right solutions for your specific needs.
